I can't seem to get ending 2, for ending 3 I did an ultra on every character and didn't die. Ending 2 I didn't do an ultra on a single enemy, so I assume to get ending 2 I need to only ultra some enemies? But what ones?

Ending 1 do no ultra on your rival ( your rival is the fighter before Fulgore ) ultra Fulgore
Ending 2 do an ultra on your rival , do not ultra Fulgore
Ending 3 do an ultra on both your rival and Fulgore

Use fighter that has all 3 endings unlock and play on med difficulty and beat all first 6 fighters without loosing

Alright well I was able to get ending 2 with Glacius so I had all three, then I stared one up on medium and barely made it through the characters without loosing barely, by the skin of my teeth (I'm not that great) and nothing. No Shadow Jago, time well spent. :\

Alright, I managed to get to him. One detail that was left out was there are some ultras that are needed somewhere. The first time I barely made it and didn't get greedy and go for ultras, I just won. This time I managed to ultra every character and it got me to Shago, so just winning every match isn't enough.

That being said, Shadow Jago is impossible, at least for someone of my skill level. Kind of depressing really, having struggled so hard to get to him on medium only to realize the hidden boss is set like three difficulty levels higher. Only hardcore motherfuckers are going to unlock that stage and that sucks.

Yep, its get all three endings and then play on Medium. Get to your rival (the fight before Fulgore) and do an Ultra Combo to win. (some are saying you have to not lose any matches either). Now instead of Fulgore you will fight Shadow Jago.

Note he is not the same Shadow Jago that you get from the Day One Xbox Live Gold subscription card. His intro is different and his moves are tweaked.

He has no Ultra combo, instead he has an ultimate combo which is pretty much a fatality combo finish. So be ready to combo break when he gets you into the flashing red.... He's aiming to finish you.

If you win, his stage unlocks and you get a 4th ending..... I smell season two and that's all I'll say in a non spoiler thread.
